They are not hurricane or storm proofed well they will develop leaks in the roof in a year as the UV rays break down the caulking that they use in a factory.

I will be taking a flashlight, gloves, drill, hammer, mask, and firearm.

I always bring a notepad for noting repairs, a flashlight, a camera or smartphone, and of course all the paperwork I'm going to need (e.g. contracts).

There's no visible evidence, aside from the 42 pound bag of cat litter.I did some research and found I can photograph urine stains if I illuminate them with a UV light. 

Any carpet cleaning company should have UV lighting systems that will show urine staid for photographic evidence.  

And the shingles probably last a little longer since the panels are blocking the UV.

There are pumps, filters and UV systems to keep going so keep that in mind.The location on the lake is also important.

If you walk through every inch of the potential investment property with a powerful flashlight to look and test for leaks, you’ll know exactly what you are purchasing.What else should investors purchasing mobile homes look out for?

I cleaned mine ok with lots of tedious caution and a little flash light, but am hesitant to recommend it as a DIY service to others since it was harder than I imagined and since I believe many AC companies will come do an annual service with coil cleaning for around $150 (again, just guesstimate) and likely have a method more foolproof than my aerosol cleaner can and garden hose, plus they can look the system over and catch/fix any small issues before a home inspector would find them.
